  • Wooden spoon
  • Baking sheet
  • Parchment paper

Ingredients
  

  • 1 sheet puff pastry (store-bought or homemade)
  • 6 strips bacon, diced
  • 2 medium onions, thinly sliced
  • 2 tbsp butter or olive oil
  • 1 tsp sugar (optional, for caramelizing onions)
  • ½ tsp salt
  • ½ tsp black pepper
  • 1 egg, beaten (for glaze)

Instructions
 

  • Caramelize onions: Heat butter in skillet. Cook onions slowly over medium-low heat for 20 minutes until golden and sweet. Add sugar if desired.

  • Cool slightly: Rest for 5 minutes before serving.

Notes

  • For extra flavor: Add shredded cheese or herbs to filling.
  • Make-ahead: Assemble rolls and refrigerate unbaked; bake fresh when needed.
  • Storage: Keep in airtight container for 3 days or freeze for 2 months.
  • Tip: Chill pastry before baking for maximum flakiness.
  • Variations: Try spicy jalapeño, vegetarian mushroom, or mini bite-sized rolls for parties.
